Wheel system for traveling body

Abstract

A wheel system, adapted for incorporating with a traveling body, includes at least a pair of wheel assembly for attaching to two outer sides of the traveling body respectively. Each wheel assembly includes a reinforcing panel adapted to be provided at an edge portion of the respective outer side of the traveling body, a wheel shelter extended from the reinforcing panel that defines a wheel cavity between the wheel shelter and the reinforcing panel, and a wheel rotatably supported in the wheel cavity for supporting the traveling body on ground.

         6 . The wheel system, as recited in  claim 3 , wherein each of said wheel assemblies further comprises an attachment means for rotatably supporting said wheel in said wheel cavity, wherein said attachment means contains a wheel axle mounted between said reinforcing panel and said wheel shelter, a through hole provided on said wheel cover, and a tubular holder, having a predetermined size, protruded from said reinforcing panel wherein said wheel axle passes through said through hole and a center hole of said wheel until an inner end of said wheel axle inserted into said holder.  
     
     
         7 . The wheel system, as recited in  claim 1 , wherein each of said wheel assemblies further comprises an attachment means for rotatably supporting said wheel in said wheel cavity, wherein said attachment means contains a wheel axle mounted between said reinforcing panel and said wheel shelter, and a pair of first and second through holes provided on said reinforcing panel and said wheel shelter respectively, wherein said wheel axle passes through said second through hole and inserts into said first through hole through a center hole of said wheel.  
     
     
         8 . The wheel system, as recited in  claim 2 , wherein each of said wheel assemblies further comprises an attachment means for rotatably supporting said wheel in said wheel cavity, wherein said attachment means contains a wheel axle mounted between said reinforcing panel and said wheel shelter, and a pair of first and second through holes provided on said reinforcing panel and said wheel shelter respectively, wherein said wheel axle passes through said second through hole and inserts into said first through hole through a center hole of said wheel.  
     
     
         9 . The wheel system, as recited in  claim 3 , wherein each of said wheel assemblies further comprises an attachment means for rotatably supporting said wheel in said wheel cavity, wherein said attachment means contains a wheel axle mounted between said reinforcing panel and said wheel shelter, and a pair of first and second through holes provided on said reinforcing panel and said wheel shelter respectively, wherein said wheel axle passes through said second through hole and inserts into said first through hole through a center hole of said wheel.  
     
     
         10 . The wheel system, as recited in  claim 7 , wherein an inner end of said wheel axle has an outer portion adapted for rotatably screwing into a mounting hole which has an inner thread portion formed on said respective outer side of said traveling body in order to rotatably support said wheel by said wheel axle.  
     
     
         11 . The wheel system, as recited in  claim 8 , wherein an inner end of said wheel axle has an outer portion adapted for rotatably screwing into a mounting hole which has an inner thread portion formed on said respective outer side of said traveling body in order to rotatably support said wheel by said wheel axle.  
     
     
         12 . The wheel system, as recited in  claim 9 , wherein an inner end of said wheel axle has an outer portion adapted for rotatably screwing into a mounting hole which has an inner thread portion formed on said respective outer side of said traveling body in order to rotatably support said wheel by said wheel axle.
